The ink discharge outlet 312 of the chamber in one end of ink path of navigation 420 and the liquid residue sensor 31 is communicated with, and the other end is communicated with ink inflow entrance 431 in being arranged on surge chamber 430, and this ink path of navigation 420 is used up sensor liquid path of navigation 400 via the upstream side ink ink in the bottom ink accommodating chamber 390 is guided to surge chamber 430.This ink path of navigation 420 is provided with in the mode that the ink discharge outlet 312 of the chamber in liquid residue sensor 31 extends obliquely upward, and the flow direction by the liquid in the liquid path of navigation interconnects a pair of ink accommodating chamber 390,430 for the mobile rising type of rising that flows from bottom to top connects.

That is, in above-mentioned figure in the illustrated cartridge body 10, three ink accommodating chambers 370,390,430 are interconnected to have the decline type and connects and be connected with the rising type.

Ink path of navigation 440 is the ink flow paths that ink guided to differential valve 40 from the ink discharge outlet 432 of surge chamber 430.

In addition, the ink inflow entrance 372,391,431 of above-mentioned each ink accommodating chamber all in each ink accommodating chamber, be arranged on each ink accommodating chamber diapire 375,395,435 near.

Below, at first illustrate from as the top ink accommodating chamber 370 of main ink accommodating chamber ink path of navigation to ink supply aperture 50 with reference to Fig. 8～Figure 12.

Top ink accommodating chamber 370 is ink accommodating chambers of the upstream (higher level) in the cartridge body 10, and forms in the face side of cartridge body 10 as shown in Figure 8.This top ink accommodating chamber 370 is the only about half of ink housing regions that account for the ink accommodating chamber, in roughly half part formation up of cartridge body 10.The ink discharge outlet 371 that is communicated with ink path of navigation 380 is at recess 374 place's openings of the diapire of top ink accommodating chamber 370.This ink discharge outlet 371 is compared with rib 10a as the diapire of top ink accommodating chamber 370 and is positioned at the below, even therefore the ink level in the top ink accommodating chamber 370 drops to diapire, this ink discharge outlet 371 is compared with the liquid level of this moment and still is positioned at the below, thereby can continue stably to derive ink I.

As shown in Figure 9, ink path of navigation 380 forms in the rear side of cartridge body 10, ink is directed into the bottom ink accommodating chamber 390 of below from the top.

Bottom ink accommodating chamber 390 is to import the ink accommodating chamber that is stored in the ink I in the top ink accommodating chamber 370, as shown in Figure 8, this bottom ink accommodating chamber 390 is the face side only about half of ink housing regions that form, that account for the ink accommodating chamber in cartridge body 10, in roughly half part formation down of cartridge body 10.Near as the rib 10a of the diapire of this bottom ink accommodating chamber 390, the connection stream place opening of the ink inflow entrance 391 that is communicated with ink path of navigation 380 below the diapire 395 that is disposed at bottom ink accommodating chamber 390 is communicated with stream from the ink I of top ink accommodating chamber 370 via this and flows into.

Bottom ink accommodating chamber 390 is used up sensor liquid path of navigation 400 by the ink discharge outlet 311 that has run through diapire 395 with the upstream side ink and is communicated with.Use up in the sensor liquid path of navigation 400 dimensional topography at the upstream side ink and become to have lost stream, catch the bubble that before ink is used up, flows into etc. by this lost stream and make it can not flow to the downstream.

The upstream side ink is used up sensor liquid path of navigation 400 and is used up sensor liquid path of navigation 410 via not shown through hole and downstream ink and be communicated with, and ink I uses up sensor liquid path of navigation 410 via the downstream ink and is imported into ink surplus sensor 31.

The ink that is imported into ink surplus sensor 31 is imported the ink path of navigation 420 that the rear side in cartridge body 10 forms by the chamber (stream) in the ink surplus sensor 31 from the ink discharge outlet 312 as the outlet of chamber.Ink path of navigation 420 forms ink from ink surplus sensor 31 guiding oblique uppers, and is connected with the ink inflow entrance 431 that is communicated with surge chamber 430.Thus, the ink that flows out from ink surplus sensor 31 is imported into surge chamber 430 via ink path of navigation 420.

Surge chamber 430 is to divide the little space that forms by rib 10a between top ink accommodating chamber 370 and bottom ink accommodating chamber 390, forms the ink storage space that was right after before differential valve 40.It is relative with the dorsal part of differential valve 40 that surge chamber 430 forms, and ink I is via discharging the 432 ink path of navigation 440 that are communicated with and flow into differential valve 40 with the ink at recess 434 places that are formed on surge chamber 430.

The ink that flows into differential valve 40 is directed to the downstream by differential valve 40, and is directed to outlet stream 450 via through hole 451.Outlet stream 450 is communicated with ink supply aperture 50, and ink I is supplied to the inkjet recording device side via the ink supply pin 240 that is inserted in the ink supply aperture 50.

Then, illustrate from atmosphere opening hole 100 to the atmosphere communication path 150 of top ink accommodating chamber 370 with reference to Fig. 8～Figure 12.

In case the ink I in the print cartridge 1 is consumed and causes print cartridge 1 pressure inside to reduce, the atmosphere (air) suitable with the reduction of the ink I that is stored be 100 inflow top ink accommodating chambers 370 from the atmosphere opening hole.

The aperture 102 that is arranged on the inside in atmosphere opening hole 100 is communicated with an end in the snake road 310 that forms in the rear side of cartridge body 10.Snake road 310 is the serpentine path that slenderly form, and has prolonged from atmosphere opening hole 100 to the distance of top ink accommodating chamber 370 and has suppressed the evaporation of the moisture the ink.The other end in snake road 310 is connected with gas-liquid separation filter 70.

Bottom surface at the 70a of gas-liquid separation chamber that constitutes gas-liquid separation filter 70 is formed with through hole 322, is communicated with space 320 in the face side formation of cartridge body 10 via through hole 322.In gas-liquid separation filter 70, between the other end in through hole 322 and snake road 310, dispose gas-liquid separation membrane 71.Gas-liquid separation membrane 71 is formed by the net of weaving into the fibrous material of high hydrophobicity, high oleophobic property.

When the face side of cartridge body 10 is observed, space 320 forms in the upper right side of top ink chamber.In space 320, through hole 321 is at the upper opening of through hole 322.Space 320 links stream 330 via this through hole 321 with the top of side formation overleaf and is communicated with.

Top links stream 330 to have: circuit portion 333, extend to the right when when rear side is observed, growing the limit from through hole 321 edges; And circuit portion 337, turning back near return portion 335 places minor face, by than circuit portion 333 position near the upper face side of print cartridges 1, and extends near the through hole 341 of formation through hole 321.This top links the top side of stream 330 by print cartridge 1, be the part of the top of the gravity direction under the state that has been mounted of print cartridge 1.Through hole 341 and the ink that forms in face side are caught and are deposited chamber 340 and be communicated with.

Here, when observing this top binding stream 330 from rear side, the circuit portion 337 that extends to through hole 341 from return portion 335, be provided with the position 336 that formed through hole 341 and on the box body thickness direction than position 336 recessed darker recess 332, and be formed with a plurality of ribs 331 that separate this recess 332.In addition, extend to the circuit portion 333 of return portion 335 than the depth as shallow that extends to the circuit portion 337 of through hole 341 from return portion 335 from through hole 321.

In addition, in above-mentioned print cartridge 1, link stream 330, so ink I can not flow through basically that top links stream 330 and to atmosphere opening hole 100 side shiftings because the part in the top of gravity direction forms top.In addition, top links stream 330 and has not the thickness degree that the broad that ink I flows backwards can take place owing to capillarity etc., and can easily catch the ink I that refluence is come owing to be formed with recess 332 in circuit portion 337.

When face side is observed, ink is caught and is deposited the space that chamber 340 is rectangular shapes of forming of the top-right corner positions in cartridge body 10.As shown in figure 12, when when face side is observed, through hole 341 is opening near ink is caught inboard bight, the upper left side of depositing chamber 340.In addition, ink catch deposit chamber 340 the lower right at the moment the bight of side be formed with as the part of the rib 10a of spaced walls cut notch 342, via this notch 342 be connected surge chamber 350 and be communicated with.Here, ink is caught and deposited chamber 340 and link surge chamber 350 is air chambers that the form with the volume midway that enlarges atmosphere communication path 150 forms, and forms ink I is stored catch at this ink and deposits chamber 340 and link the surge chamber 350 and make ink I can not continue to flow to atmosphere opening hole 100 1 sides as far as possible even this ink catches to deposit chamber 340 and link surge chamber 350.The back will illustrate that ink catches the concrete effect of depositing chamber 340 and linking surge chamber 350.

Binding surge chamber 350 is caught at ink and is deposited the space that forms below the chamber 340.The bottom surface 352 that links surge chamber 350 is provided with the vent 110 that is used for vacuumizing when injecting ink.In addition, near bottom surface 352, be positioned in the time of on being installed to inkjet recording device gravity direction below the position, through hole 351 is to the thickness direction side opening, the liquid path of navigation 360 that forms via this through hole 351 and side overleaf is communicated with.

When rear side is observed, liquid path of navigation 360 extends to central upper side, is communicated with top ink accommodating chamber 370 via near the through hole 372 of the opening bottom surface of top ink accommodating chamber 370.That is, the part from atmosphere opening hole 100 to liquid path of navigation 360 has constituted the atmosphere communication path 150 of above-mentioned print cartridge 1.Liquid path of navigation 360 forms the thickness degree that can form meniscus (meniscus) and ink I can not be flow backwards.

And, in above-mentioned print cartridge 1, as shown in Figure 8, except above-mentioned ink accommodating chamber (top ink accommodating chamber 370, bottom ink accommodating chamber 390, surge chamber 430), air chamber (ink is caught and deposited chamber 340, connects surge chamber 350), ink path of navigation (the upstream side ink is used up sensor liquid path of navigation 400, the downstream ink is used up sensor liquid path of navigation 410), also divide in the face side of cartridge body 10 and to be formed with the not filled chamber 501 of filling ink I.

Filled chamber 501 is not zones of the close left surface represented with hacures in the face side of cartridge body 10, is divided to form by top ink accommodating chamber 370 and bottom ink accommodating chamber 390 clampings.

And, be not provided with the atmosphere opening hole 502 that is through to rear side in the upper left corner of the interior zone of filled chamber 501 at this, be communicated with extraneous gas by this atmosphere opening hole 502.

This is filled chamber 501 degas chamber of the degassing with negative pressure that become pressure accumulation when print cartridge 1 having been carried out decompression bag (pack) packing not.

In the print cartridge 1 of above explanation, for example the print cartridge of having pulled down from carriage 200 when way in use 1 has been toppled over or has been installed under the state on the carriage 200 because the influence of external vibration when waiting ink level in each ink accommodating chamber 370,390,430 to rock, in the few ink accommodating chamber of ink surplus, the air layer ink path of navigation that can contact with the ink discharge outlet in this accommodating chamber and cause bubble B to enter into being communicated with sometimes with ink discharge outlet.

But, structure according to above-mentioned print cartridge 1, because three ink accommodating chambers 370,390,430 are interconnected to and have the decline type and connect and be connected with the rising type, therefore the liquid path of navigation till the ink supply aperture 50 becomes crooked up and down stream, and the ink I that remains in the liquid path of navigation of decline type becomes the protection walls that the prevention bubble is advanced.Therefore, the bubble B that enters into the ink path of navigation is difficult to enter the downstream.

In addition, the ink path of navigation that the rising type connects connects as the decline type under the situation that the print cartridge 1 that removes from carriage 200 has turned upside down and plays a role, and stops bubble side shifting downstream.That is,, also can obtain to stop the bubble effect of side shifting downstream by the connection of decline type even print cartridge 1 turns upside down.

And, the ink accommodating chamber 390,430 that is connected after the second level is deposited the space and is brought into play function as catching catching of the bubble that flows into from the top ink accommodating chamber 370 of upstream, in case for example print cartridge 1 has become the state of laying across, become the state that extends in the horizontal direction at the upwardly extending stream of upper and lower, then the decline type connection each other of ink accommodating chamber can't be brought into play the effect that stops bubble to move fully.But, even in this case, the upper space of each ink accommodating chamber 390,430 also can be as catching of the bubble that flowed into deposited the space and is brought into play function effectively, the ink I that remains in this ink accommodating chamber 390,430 plays a role as the protection walls that stops bubble to move downstream, thereby can stop bubble to move downstream reliably.

In addition, even bubble B enters into ink path of navigation 380 from higher level's ink accommodating chamber 370, also can in the reclinate ink path of navigation 380 that mutually links the ink accommodating chamber, ink accommodating chamber 390, exist spendable ink surplus during in suppress to enter into the ink path of navigation bubble B arrive the detection position of ink surplus sensor 31, thereby can avoid occurring because bubble enters the problem that causes the 31 generation flase drops surveys of ink surplus sensor and cause the unexhausted quantity of ink that goes out of use to increase.

In above-mentioned print cartridge 1, in a cartridge body, divide and be formed with three ink accommodating chambers, but the quantity that is arranged on the ink accommodating chamber in the cartridge body can be any amount more than three, the ink accommodating chamber that quantity is set is many more, bubble catches that deposit can multipleization, thereby the performance that stops bubble to move downstream can improve.Particularly compare with the liquid residue sensor ink accommodating chamber, the decline type that are positioned at the upstream be connected be connected with the rising type that quantity is set is many more, can suppress the detection position that bubble arrives the liquid residue sensor more reliably.

Then, illustrate when the ink I in the print cartridge 1 of above explanation is depleted according to Figure 13, Figure 14 or in this print cartridge that uses 1, inject an embodiment of the method for ink when being reduced to scheduled volume.

At first, the reinject formation of device of the ink that uses is described in the renovation process of present embodiment.

As shown in figure 13, the ink device 600 that reinjects comprises: ink injection unit 610 that is connected with the inlet of offering on cartridge body 10 by boring processing 601 and the vacuum attraction unit 620 that is connected with the ink supply aperture 50 of cartridge body 10.

Ink injects unit 610 and comprises: store the valve 614 that China ink jars 611 that the ink that will fill is arranged, the ink force feeds in should China ink jar 611 are given the pump 613 and the conducting between this pump 613 and inlet 601 of the stream 612 that is connected with described inlet 601, blocked stream 612.

Vacuum attraction unit 620 comprises: vavuum pump 621 produces the needed negative pressure of vacuum attraction; Liquid path of navigation 622 makes the suction function that is produced by this vavuum pump 621 in ink supply aperture 50; Ink is caught storage 623, is arranged on liquid path of navigation 622 midway, catches, reclaims because vacuum attraction and ink from cartridge body 10 side inflows to liquid path of navigation 622, and protection vavuum pump 621 is avoided damages such as ink mist; And valve 624, catch conducting between storage 623 and the ink supply aperture 50, blocking-up liquid path of navigation 622 at this ink.

In the present embodiment, consider the structure and the function of print cartridge 1, the formation position of inlet 601 in atmosphere communication path 150 that is communicated with top ink accommodating chamber 370 is positioned near the position relative with through hole 372, and described through hole 372 is positioned at the downstream of the liquid path of navigation 360 of a part that constitutes atmosphere communication path 150.

And, form the inlet 601 relative with through hole 372 by consistently on the appearance facial mask 60 of the rear side that covers cartridge body 10, offering the hole with through hole 372.In case inserting the top ends of the stream 612 of this inlet 601 for example is provided with and has run into through hole 372 then hermetic be close to the container wall around the through hole 372 and make stream 612 and through hole 372 become the sealing ring etc. of the state of being tightly connected.

Inlet 601 on the cartridge body 10 is so long as the inlet that is formed in the atmosphere communication path 150 gets final product the position is set needn't be defined in the position relative with through hole 372 especially of inlet 601 with the form that the top ink accommodating chamber 370 of upstream is communicated with.For example, form under the situation of inlet 601 in rear side from cartridge body 10, as shown in figure 14, can with regional corresponding, the position that is provided with that is not set at inlet 601 of top ink accommodating chamber 370 with the suitable position P2 of snake road 310 that is arranged on rear side or 380 interferences of ink path of navigation.

In the method for implanting of present embodiment, at first be regenerated as the regeneration print cartridge (regeneration liquid housing container) that can reuse by implementing the print cartridge 1 that following operation uses successively: inlet forms operation, and inlet 601 is communicated with top ink accommodating chamber 370 to atmosphere communication path 150 openings; The vacuum attraction operation attracts to remove ink and the residual gas that remains in inside by vacuum attraction unit 620 from ink supply aperture 50; The liquid filling work procedure injects unit 610 injects scheduled volume from inlet 601 ink by ink; Sealing process finishes back sealing inlet 601 at the liquid filling work procedure.

Sealing process is specifically by bonding or deposited diaphragm seal or band etc. or the treatment process of hermetic sealing inlet 601 by stopper etc.

In the renovation process of the print cartridge 1 of the above present embodiment that has illustrated, the processing of print cartridge 1 being carried out in order to inject ink I comprises: be used in inject ink inlet 601 to atmosphere communication path 150 openings and the processing that is communicated with the top ink accommodating chamber 370 of upstream and filled ink I after seal the processing of inlet 601, both are simple processing.Therefore, processing cost is low, saves man-hour and labour in addition.

And, in the renovation process of present embodiment, owing to have to attract to remove and remain in the inner ink and the vacuum attraction operation of residual gas from ink supply aperture 50, therefore at the liquid filling work procedure that injects the ink of scheduled volume from inlet 601, each ink path of navigation 380 with cartridge body 10,420,440 and each ink accommodating chamber be controlled to reduced pressure atmosphere, the ink that has injected not only can be filled into ink accommodating chamber 370 effectively, 390, in 430, but also the ink that has injected can be filled into effectively to all ink path of navigation of ink supply aperture 50 everywhere.

In addition, the bubble that can also sneak into when the outside is discharged at filling ink I from ink supply aperture 50 by vacuum attraction, disappears in the liquid gas bubble that has perhaps utilized the reduced pressure atmosphere that forms in container by vacuum attraction to make to flow into.

Therefore, the bubble B that sneaks into when injecting ink I can not swim in ink accommodating chamber or ink path of navigation or adhere to, remains on the stream wall, and for example also can not take place has bubble B to cause the liquid residue sensor can't the such unfavorable condition of operate as normal owing to residual near the test section of liquid residue sensor.

In addition, the position that inlet 601 is set is the flow of ambient air path that is communicated with the top ink accommodating chamber 370 of upstream, therefore a plurality of ink accommodating chambers of all in being arranged on cartridge body 10 and link mutually in the liquid path of navigation of ink accommodating chamber and inject ink swimmingly.

Therefore, injecting the regeneration print cartridge 1 of ink, the ink path of navigation 380 and the ink path of navigation 420 that is connected the liquid path of navigation of ink accommodating chamber as the rising type that connect the liquid path of navigation of ink accommodating chamber by conduct decline type, restored crooked up and down flow path configuration, even produced bubble B in the ink accommodating chamber 370 of upstream, the ink I that remains in the liquid path of navigation of decline type also can become the protection walls that stops bubble to move downstream.Therefore, the bubble B that enters into ink path of navigation 380 is difficult to enter the downstream.

In addition, except the crooked up and down stream of mutual binding ink accommodating chamber, therefore the upper space of each ink accommodating chamber 390,430 in downstream can stop bubble B to move downstream as catching of the bubble that flowed into being deposited the space and playing a role effectively.

That is, the bubble of the liquid path of navigation between the ink accommodating chamber 380,420 bubble of catching the ink accommodating chamber 390,430 of depositing function and downstream is caught and is deposited function and also revert to identical with the print cartridge 1 of coming of new.

Therefore, the bubble B that can similarly suppress to enter into from the ink accommodating chamber ink path of navigation with the print cartridge 1 of coming of new arrives the detection position of ink surplus sensor 31, thereby can avoid occurring because the problem that entering of bubble causes the survey of liquid residue sensor generation flase drop and cause the unexhausted quantity of ink that goes out of use to increase.

Promptly, renovation process according to the print cartridge 1 of present embodiment, when in the print cartridge 1 that uses, injecting ink, print cartridge 1 is carried out a spot of processing and get final product, and can under the situation of the various functions of not damaging this print cartridge 1, inject ink, thereby can make regeneration print cartridge 1 at low cost.

And, if the regeneration of regenerating by such renovation process print cartridge is provided, can prolong the life of product as container of print cartridge, therefore can help economizing on resources, preventing the pollution of the environment.In addition, can provide the regeneration print cartridge with low cost, therefore also help the use cost that reduces inkjet recording device because the needed cost of regeneration is low.

In the above-described embodiment, the position that inlet 601 is set is the atmosphere communication path that is communicated with the top ink accommodating chamber 370 of upstream, but is not limited thereto.For example, inlet is formed on film 60, film 80 or the cartridge body 10 directly is communicated with top ink accommodating chamber 370.

Specifically, both can on the appearance facial mask 60 of the rear side that covers cartridge body 10, offer the hole and form the inlet that directly is communicated with top ink accommodating chamber 370, and also can remove cover 20 in addition and expose the also inlet that directly is communicated with of formation and top ink accommodating chamber 370 of film 80.And, can also form inlet on the cartridge body 10 of film 60 deposited.
